Letters Patent No. 98,433, dated December 28, 1869.

IMPROVEMENT IN CARRIAGE-SPRINGS.

The Schedule referred to these Letters Patent and making part. of the Hague To all whom it may concern Be it known that I, DANIEL SHocKEY, of Waynesborough, in the county of Franklin, and State of Pennsylvania, have invented a new and improved Carriage- Spring; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the accompanying drawings, making a part of this specification, in which the figure is a side elevation.

This invention relates to a spring-apparatus, in which the cross-bars, on which the carriage immediately rests, move on vertical guide-bars projecting from the axles, and springs are interposed to check the downward movements of such cross-bars.

The invention consists in interposing springs to check the-upward movements of such guide-bars.

In the drawings- A is the axle; and A, the cross-bar on which one end of the carriage immediately rests.

Elliptic springs B B are interposed between the axle and cross-bar, and three or more bars a project upward from the axle, and from the guides, on which the struts a, projecting downward from the cross-bar, p y- Rubber cushions a, placed on the guide-bars (5,,1'3- ceive the impact of the struts as they descend. I acknowledge the foregoing to be a common arrangement.

What is especially new in this invention is the interposition of the rubber cushions 1) between the lower ends of the struts and the upper ends of the vertical guide-bars a. Such cushions receive the impact of the struts when they are thrown upward, and, by their use in connection with the cushions a, the apparatus is padded at all pointswhere jars may originate.

Having thus described my invention,

\Vhat I claim as new, and desire to secure by Letters Patent, isa The combination of the guide-bars a, struts a',cushions a" b, axle A, and cross-bar A, in the manner and for the purpose specified,

To the above specification of my improvement I have set my hand, this 10th day of November, 1869.

DANIEL SHOGKEY.
